The rational behind the cut-off test of 1 months before and after the cut-off date comes from the fact that the import condition for the company is normally CIF
which means that the title over goods transfer to the client when the goods arrive at Thailand.
Normally, invoice will be received along with imported goods and, after receiving the goods, production department will forward invoice to K. Suchada and this could take at most 1 day.
However, like the recording of export sales, K. Suchada will wait for the shipping company's invoice before she could record the purchase.
K. Suchada informed us that the lap time between the arrival of shipment and the receipt of shipping invoice is normally one week.
K. Suchada usually follows-up on shipper's invoice at the end of the month so the risk of under-recording purchase can be mitigated.
From the discussion with K. Suchada, the import normally is made from Japan and the longest shipment duration from Japan to Thailand
is no longer than 1 month (by ship) (as confirmed by our CAKE).
So, in order to ensure that the shipment that arrived within the accounting date was recorded in the proper period, we inspect the invoice issued within the date of
1 month before and after the cut-off date as the client doesn't use Goods Receipt Note to record purchase but use the vendor invoice and shipping document instead.
